What are the solutions of x2 + 10x + 16 = 0?
Elza [17]

Answer:

(x+2)(x+8)=0

Step-by-step explanation:

the first term x² can only be factored by (x) times(x), and the last term 16 has factors of 16&1, 4&4 or 8&2. only 8 &2 have a sum of 10x (the middle term) so

(x+2)(x+8)=0

You bake a batch of muffins. You freeze 6 muffins and share the rest equally among yourself and 2 friends. Write an expression t
Tatiana [17]

Answer:

m=\displaystyle \frac{t-6}{3}

Step-by-step explanation:

Hi there!

Let <em>t</em> equal the total number of muffins.

t-6 ⇒ This represents freezing the 6 muffins

\displaystyle \frac{t-6}{3} ⇒ This represents sharing the remaining muffins among 3 people

Therefore, the expression would be \displaystyle \frac{t-6}{3}.

If you would like to change this into an equation, it would be m=\displaystyle \frac{t-6}{3}, where <em>m</em> is the number of muffins that each person gets.

I hope this helps!

Rewrite (3x + 2)(x - 3) in standard form
ludmilkaskok [199]

Answer:

3x^2-7x+6

Step-by-step explanation:

Standard from: ax^2+bx+c

(3x+2)(x-3)

We just need to multiply these two binomials together.

When doing multiplication we get:

3x^2-9x+2x-6

3x^2-7x+6

This is in standard form so the answer is 3x^2-7x+6
